I have terrible indoor/outdoor allergies. I used Zertec alone and it helped a little in the day to day, but not when I am exposed to heavy-duty allergens. I went home to my parent's family farm for Christmas break and expected to be miserable. I brought Nettle with, and used it in conjunction with Quercetin and Zertec, and I was allergy free for the entire three weeks I was home.
I recommend this product.

In addition to its calming effect, helping to reduce inflammation, and usefulness for Allergies, I take nettle in place of calcium supplement. I am a 46 year old female who does not take calcium supplement or dairy but taking nettle herb has kept my calcium levels nicely in the reference range!

I love this product! I use this and olive leaf extract to keep my sinus congestion (which gen would lead to an asthma flairup)in tack. Thank god i have not had an asthma attack in 2 years!!...to where as before i was taking all kind of asthma meds and nasal steroids and paying alot for meds and md bills that were NOT HELPING! God bless iherb!i feel so fortunate to have found them .They offer GREAT prices and i LOVE THAT YOU CAN READ THE TESTIMONIALS OF THE PRODUCTS AND THERE USES!

These are great for hay fever and seasonal allergies in spring and summer where all the pollen is out. Note that it may lower blood pressure a little (which can be good or bad or neither). Stinging Nettle is different from other nettles and it seems to be very useful in many ways to middle aged to older men in the south east United States.

This stuff works the best for allergies, by far! I used to take a few when I felt my allergies coming on and it helped BUT you really need to take it all the time for the full effect. I take one in the morning and one in the evening (been doing so for about 2 months now) and my eyes haven't watered, itched, or burned and I barely sneeze at all. I skipped a couple days while waiting to reorder and I was sneezing all over the place! My boyfriend has excruciating allergies and since taking Nettle regularly, he has had minimal symptoms. This is even safe to sprinkle in your pet's food if he/she has allergies--my one cat gets a runny eye and the sneezies every now and then and half a capsule in her food clears it right up (and it has no taste so she doesn't even know it's in there). Also, iherb has the BEST prices, customer service, and fastest shipping out there!
